Space exploration was a major aspect in Ratchet & Clank Future: A Crack in Time. It was a new feature added, that expanded the space gameplay that Ratchet endured in the previous games. The space exploration feature allowed Ratchet to explore the space inbetween planets and moons and aided him on his journey. Via this, he could land on spherical worlds, pick up objects in space and collect Zoni. Space combat was also a part of space exploration. Ratchet piloted Aphelion through outer space. Using new introduced technology, he could pick up space objects and use them to complete side-quests. This was also another way of reaching other planets and moons.
